Subject: [PATCH v1 06/10] bus/vmbus: define Hyper-V page size
Date: Fri, 25 Apr 2025 02:07:54 +0000 [thread overview]
Message-ID: <20250425020758.3794-6-kyo.liu@nebula-matrix.com> (raw)

From: Long Li <longli@microsoft.com>
Hyper-V uses 4k page size, regardless of the system page size used. Define
Hyper-V page size for use in drivers.
